® RT5707/A Ultra-Low Quiescent Current HCOT Buck Converter General Description The RT5707/A is a high efficiency synchronous step-down converter featuring typ. 360nA quiescent current. It provides high efficiency at light load down to 10mA. Its input voltage range is from 2.2V to 5.5V. The RT5707 provides eight programmable output voltage 1.2V to 3.3V while delivering output current up to 600mA, peak to 1A. The RT5707A provides eight programmable output voltage 0.7V to 3.1V while delivering output current up to 400mA, peak to 0.5A. The Hysteretic Constant-On-Time (HCOT) operation with internal compensation allow the transient response to be optimized over a wide range of loads and output capacitors. The RT5707/A is a available in WL-CSP-8B 0.9x1.6 (BSC) package.
